I want to number the rows in my datagridview.

Row Headers Of Datagridview Are Empty On Formload

Apr 6, 2009

I use a datagridview where the rowheaders frustratingly stay blank after I load the form. If I modify/add/delete anything the rowheaders pop up. then when I sort by clicking on a columnheader the rowheaders become blank again. all these actions (load/add/modify/sort) go through the same refresh function. I can't seem to figure out why the rowheaders sporadically show up. they should stay visible all the time. btw, datagridview.refresh() doesn't work

Custom ComBobox With Headers - Prevent Selection Of Headers?

Dec 15, 2009

I am working on a windows application using VB.net 2.0 and want to create a custom ComboboxControl which displays multiple groups. I was able to display the items in Custom combobox with headers. Below is the sample.

Header 1
Item 1_1
Item 1_2

[code]....

I want to prevent users from selecting the header items. I managed to revert back to the previously selected item if user selects the header item. Problem with this approach is drop down collapses and then reverts back to previously selected item. Is there a way to check, if the item being selected is a header item and if it is a header item, do not collapse the dropdown. Basically I want to implement behavior of HTML select list with optgroup.

1_1 1_2 1_3 2_1 2_2 2_3

Importing Data From Excel To Datagrid Or Datagridview?

May 5, 2010

I have a problem loading big spreadsheets into a datagridview.

I had a similar code as above that i used and it works great if you have say 10000 cells to populate cell by cell.

How ever moving to 2 mil cells is a different cup of tea, the code took more than 7 minutes to load the data, and although the data was perfect in every way, its too time consuming, i cant get it to work faster so I used the datagrid instead.

The sheets needed to be imported is 350,000 cells plus. I used code that works realy great, does the import into the grid and transfers the data to a datagridview within 15 seconds with little resources which put a smile on my dail :) then i saw something and it dropped ...

see code:

[Code].....

My problem is that whenever there are values below the heading of the cell the datagrid displays (null)

No matter what i do even converting the values in excel to text it does not display the heading of that column.

When i paste other text into the cells below the heading (NOT NUMBERS) it shows the data and heading, Only if the "type" of content is the same does it display both the heading and the text that follows in rows below.

I'm using a datagridview to display data from an Access database. Is there a way to have the columns that are imported be set to fill up the entire datagridview? depending on what data I'm displaying the columns are either too narrow or too long for the datagridview. I'd like them to always just fill up the entire space in the datagridview without having scroll bars or empty space.
